Parallel and serial transmission

Digital data transmission can occur in two basic modes: serial or parallel. Data within a computer system is transmitted via parallel mode on busses with the width of the parallel bus matched to the word size of the computer system. Data between computer systems is usually transmitted in bit serial mode

In parallel transmission, multiple bits (usually 8 bits or a byte/character) are sent simultaneously on different channels (wires, frequency channels) within the same cable, or radio path, and syncorised to a clock

USB
